Simplify PR welcome messages (#2009)

## Summary
Simplified both PR welcome message workflows to be more concise by
reducing verbose explanations to single-line summaries.

## Changes
- Condensed multi-paragraph welcome messages into one line
- Removed bullet-point lists of what full CI does
- Kept essential info: how to trigger full CI with `/run-skipped-ci`
- Eliminated redundant content between the two workflows

## Before
Both workflows showed lengthy explanations with:
- Multiple paragraphs about CI behavior
- Bullet lists of what tests run
- Detailed notes about permissions and labels

## After
Single concise line: "**Need full CI coverage?** Comment
`/run-skipped-ci` to test against minimum supported versions (Ruby 3.2,
Node 20) and all test matrices."

## Summary by CodeRabbit

* **Chores**
* Removed automated PR welcome comments and simplified CI notification
messaging.
* Simplified the "run skipped CI" feedback to remove verbose per-check
listings.
* **New Features**
* Introduced a "full-ci" label flow that lets maintainers request full
test coverage on demand, enabling full lint/test runs and broader
dependency matrices when applied.
